Video call (center)

We are starting to develop a new application, and I'm looking for information / tips / guides on application architecture.

The application should:

  • read data from an external (USB) device
  • send data to a remote server (via the Internet)
  • receive data from a remote server
  • make a video call with the calling (supporting) center
  • receive a video call from the call center (support)

  • touch screen support

  • In addition: some data should also be visible through a web page.

So, I thought: Server side:

  • use a database (possibly MS SQL)
  • use ORM (nHibernate) to map data from the database to domain objects
  • create a business logic layer in c #
  • create a web service (for client application)
  • create an asp.net mvc application (for clause 7.) to enable browsing of data

On the client side, I would use a WPF 4 application that will communicate with the external device and wcf services on the server.

So far so good. Now the problem begins. I don’t know how to create a video call (outgoing or incoming) part of the application. I believe that there is no problem connecting to a microphone, speaker, camera with WPF / C #. But how to communicate with the call center? What protocol and coding should I use?

I think that I will need to create some kind of server that will be:

  • have a list of agents in the calling center and keep track of which operator is busy and which operator is free
  • there is a list of connected end users
  • accept incoming calls from end users and delegate the call to a free agent
  • calling a delegate from the calling center to the end user

Any information, link, anything about where to start would be greatly appreciated.

Many thanks!

I suggest using the existing service (Skype, Google Chat, ...) and controlling if from your application (s) WPF for the operator and client.

It seems that you are working in the field of support, and not in creating software for video conferencing. Perhaps look at licensing a third-party SDK to populate the application’s video conferencing component. It should be much faster to get your application live than to reinvent the wheel. I quickly googled for "SDK video conferencing." Several popped up immediately. I never used them, so I'm not going to recommend them, but I think this is a good place to start.

Use a SIP solution with a video codec. There are many SIP SDKs as standard.
